- A
Use Amazon CloudWatch Events to match S3 API calls from CloudTrail and route to an SQS queue.
Why wrong: This adds latency and complexity. CloudTrail delivers logs within ~15 minutes, not real-time. S3 event notifications are more direct and timely.
- B
Configure an S3 event notification on the bucket to send events to an SQS queue.
This is the simplest and most efficient method. S3 can publish object-level events directly to SQS with minimal delay.
- C
Deploy an application that periodically polls S3 for changes using ListObjects.
Why wrong: Polling is inefficient, not real-time, and introduces significant overhead compared to event-driven notifications.
- D
Use AWS CloudTrail to deliver logs to CloudWatch Logs, then create a metric filter and trigger a Lambda function to send to SQS.
Why wrong: This is overly complex and introduces delays from CloudTrail log delivery and processing.
Quick Answer
The answer is to configure an S3 event notification on the bucket to send events directly to an SQS queue. This is correct because Amazon S3 natively supports publishing event notifications for object-level operations—such as PUT and DELETE—straight to an SQS queue without requiring any intermediate services like Lambda or custom polling logic. This native integration minimizes operational overhead by eliminating the need for additional infrastructure or code, making it the simplest and most efficient solution for downstream processing. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of S3 event-driven architectures and the direct service integrations available; a common trap is overcomplicating the solution by introducing unnecessary components like Lambda when S3 can publish directly to SQS. Remember the memory tip: "S3 to SQS is a direct express—no Lambda detours for object-level success."
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A SysOps administrator needs to monitor Amazon S3 for object-level operations such as PUT and DELETE events in a specific bucket. The administrator wants these events to be sent to an Amazon SQS queue for downstream processing by an application. Which solution should be used to achieve this with the least operational overhead?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure an S3 event notification on the bucket to send events to an SQS queue.
Option B is correct because Amazon S3 can directly publish event notifications for object-level operations (e.g., PUT, DELETE) to an SQS queue without any intermediate services. This native integration requires no custom code or additional infrastructure, minimizing operational overhead while meeting the requirement to send events to SQS for downstream processing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may overcomplicate the solution by choosing CloudTrail or Lambda-based approaches, forgetting that S3 has a built-in, direct event notification feature for SQS that requires no additional services.
Detailed technical explanation
How to think about this question
S3 event notifications use a publish-subscribe model where the bucket can send events to SQS, SNS, or Lambda with minimal latency (typically within seconds). The SQS queue must be in the same AWS Region as the bucket, and the bucket policy must grant S3 permission to send messages to the queue; if the queue is encrypted with SSE-KMS, additional KMS key policies are required. This integration supports filtering by event type (e.g., s3:ObjectCreated:Put) and prefix/suffix, allowing precise control over which operations trigger notifications.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
